What relationship exists between resistance and current in a circuit?

The relationship between resistance and current in a circuit is defined by Ohm's Law, which states that current (I) is equal to the voltage (V) across the circuit divided by the resistance (R). This can be mathematically expressed as I = V/R.

From this relationship, it becomes clear that if the resistance increases, while the voltage remains constant, the overall current flow will decrease. This is due to the fact that a higher resistance impedes the flow of electrons in the circuit, leading to a reduction in current.

Therefore, the statement that the greater the resistance, the less current will flow is correct as it directly aligns with the principles of Ohm's Law. As resistance increases, it acts to limit the amount of current that can flow through the circuit at a given voltage.
